Fourier Trend Energy (Prototype)

Fourier Trend Energy (Prototype)
This indicator brings the logic of Fourier-based trend analysis into Pine Script.
It estimates two key components:

Low-Frequency Energy — representing the strength of the underlying trend

High-Frequency Energy — representing noise, volatility, or deviation from the trend

🔹 Green line → trend strength
🔸 Orange line → short-term noise
🟩🟥 Background color → shows whether trend energy is increasing or decreasing

You can use it to:
Detect early trend formation
Filter fakeouts during consolidation
Spot momentum shifts based on energy crossovers

This is not a traditional oscillator — it’s a frequency-inspired tool to help you understand when the market is charging for a move.
